Since the last update i’ve been met with these SChannel Event Errors that randomly causes my Hardcore WoW Game to crash. I immediately thought it was addons, but I disabled them all and still continued to crash…

I played 1-55 Since November with the exact same setup and internet without ANY crashes or DC’s. Ever since the latest update (I believe Jan 31, 2025?) I have been crashing every single day.

Things i’ve tried:

  • I’ve completely uninstalled Battle Net and WoW.
  • I’ve completely deleted all Cache folders
  • I’ve completely reinstalled Battle Net and WoW.
  • I’ve tried Scanning and repairing the game.

SChannel Event Errors still happening.
What is going on?

What version of windows are you using?

I was able to resolve this issue permanently on my end.

Are you currently using a PiHole, pfBlockerNG, or any other network level ad-block/dns filtering on your LAN?

I had the exact same error repeatedly present in the Event Viewer, even causing crashes was because I was blocking the domain: “telemetry-in .battle .net” (delete the spaces) this wasn’t being blocked explicitly but I had regex filtering setup to block ads and domains that start with “telemetry”.

I added this to my whitelist on pfBlockerNG and now the certificate can properly download and I get no more errors.

Weirdly enough, I moved Airbnb’s lately and the SChannel Event Errors stopped for a week. Then I moved to another Airbnb and they resumed happening. Started crashing randomly in Hardcore again…

Please humor me, try connecting your PC/Laptop/device to a hotspot on your phone.

If you don’t get these errors while you’re connected to the cellular hotspot then it is likely the network at your Airbnb is filtering traffic.

From a security standpoint this is definitely something I would do if I was renting my property out for Airbnb.

Just tried on my 5G Hotspot phone (Verizon).

Still getting the SChannel Events…
